Abstract

Telemedicine system provide medical services to those who can not access it due to distance. In such systems, the patient s critical information, including medical data, images, audio and video, must be delivered to the hospital in time and in a robust fashion. Technologies such as Mobile Broadband Networks enables Telemedice, however in order to deliver these mostly delay-sensitive data, a robust communication system design is crucial. In this thesis, we design a communication system using multiple MBB links in order to minimize the delay of the different transmitted applications. We design the system in transport layer and specifically use multipath TCP (MPTCP) for data transmission. In order to reduce the application delay of different applications, we propose an algorithm called MPTCP Multi Stream (MPTCP-MS). MPTCP-MS reduces the delay of different applications by assigning these applications to specific paths. The proposed algorithm has been implemented in the linux kernel and tested in a real-world environment in Nornet Edge testbed. Our results show that the proposed algorithm outperforms the current MPTCP implementation in terms of delay and provides a viable solution to telemedicine system to transmit different data at the same time with minimum delay.
